Charlie [=McKenzie=] is a [[{{Beatnik}} beat poet]] living in UsefulNotes/SanFrancisco, after having broken up with yet another girl based on paranoid perception. His policeman friend Tony tries to point out the pattern; that Charlie simply is afraid of commitment and tries to think of, or invent, any reason to break up with someone. Things pick up again when Charlie meets a butcher named Harriet, and becomes infatuated instantly. As the plot continues, Tony realizes that Harriet may be the mysterious "Mrs. X", a BlackWidow who had married and killed multiple husbands. After marrying Harriet, HilarityEnsues when both Charlie and Tony try to discover if Charlie is in love with a serial man-killer.

Released in 1993, the movie starred Mike Myers as Charlie, Nancy Travis as Harriet, and Anthony [=LaPaglia=] as Tony. It was a box-office disappointment as it earned less than half of the movie budget while on the big screen.

Several well-known personalities made cameo shots, including Steven Wright, Alan Arkin, Charles Grodin, and Phil Hartman.
!!! '''''So I Married a Trope Murderer''''':
* AbhorrentAdmirer: Charlie's mother May Mckenzie had the hots for Tony. When he went to kiss her goodbye on the cheek she grabbed him and gave Tony a long lingering kiss to his lips. Then she called him a sexy bastard. While dancing with him at her own wedding anniversary the horny housewife held him tight and tried to make out with him.
* TheAlcatraz: Charlie and Tony do the guided tour of the prison. They always try to get the one lead by Ranger John 'Vicki' Johnson. [[CrowningMomentOfFunny For good reason.]]
* AxCrazy: Mrs. X
* BenevolentBoss: Tony's superior at the police department, as a parody of DaChief (see below). In fact, the chief even starts acting like a hardass because Tony wishes that his chief acted more stereotypical... and to hammer this trope home, he proceeds to ask for critique on his performance afterwards.
* BewareTheNiceOnes: [[spoiler:Harriet's ShrinkingViolet sister Rose turns out to be an insane serial killer]].
* BlackWidow: Mike Meyers parodies the trope -- his character believes he is dating the mysterious "Mrs. X." [[spoiler: She's not. Turns out ''her sister'' was an insane ClingyJealousGirl who murdered all of the poor girl's previous husbands (she thought they had all just up and left her).]]
* CallBack: In the last scene, Charlie revisits the poem he had written after he had broken up with Harriet, though it's reworded to be much more complimentary.
* CassandraTruth: All those tabloid articles. There really ''is'' a Mrs. X out there killing guys. Also, [[spoiler: Harriet]] at the end tells Tony exactly what's going on and how Tony needs to go save Charlie ([[FunnyBackgroundEvent while Charlie's screams for help and the sound of axe impacts can be heard in the background]]), but Tony doesn't believe it (though, to be fair, the evidence gathered so far does implicate [[spoiler: Harriet]]).
* ConspiracyTheorist: Charlie's dad:
-->'''Stuart Mackenzie''': [[Magazine/WeeklyWorldNews Well, it's a well known fact]], [[UsefulNotes/ScottishEnglish Sonny Jim]], that there's a secret society of the five wealthiest people in the world - known as [[AncientConspiracy The Pentavirate]] - who run everything in the world - including the newspapers - and meet tri-annually at a secret country mansion in Colorado, known as "The Meadows".
-->'''[[{{Corpsing}} Tony Giardino]]''': So who's in this Pentavirate?
-->'''Stuart Mackenzie''': [[AristocratsAreEvil The Queen]], [[CorruptChurch The Vatican]], [[CorruptCorporateExecutive The Gettys]], [[GreedyJew The Rothschilds]], *and* [[TheLastOfTheseIsNotLikeTheOthers Colonel Sanders]] before he [[UnusualEuphemism went tits up]]. Oh, I hated the Colonel with 'is wee *beady* eyes, and that smug look on his face. "Oh, you're gonna buy my chicken! Ohhhhh!"
-->'''[[TalkingToHimself Charlie Mackenzie]]''': Dad, how can you hate "The Colonel"?
-->'''[[SuddenlyShouting Stuart Mackenzie]]''': ''Because he puts an addictive chemical in his chicken that makes ya crave it fortnightly, '''[[BritishEnglish smartarse]]'''''!
-->'''[[TalkingToHimself Charlie Mackenzie]]''': Interesting. [[EyeTake Koo-koo!]]
* CooldownHug: ''"Somebody needs a hug!"''
* {{Corpsing}}: Tony attempts to maintain a semblance of concern for William's mental well being when Stuart berates William over the size of his head, but very quickly falls out and is nearly crying by the end.
* DaChief: Parodied - A police detective expresses dissatisfaction that his job is not more like the movies - partly because his boss, far from this trope (see above trope), is a pleasant, amiable and good-natured administrator with an easy-going temper.
* EverythingsLouderWithBagpipes: Charlie's wedding party has his dad (also play by Mike Myers) singing "[[Music/RodStewart Do Ya Think I'm Sexy]]" accompanied by bagpipes. When the old player drops, dad announces "We have a piper down!"
* FlashedBadgeHijack: Subverted when a cop stops a passing motorist, but can't get him to give up his vehicle. He has to settle for getting a ride from the driver to the crime-in-progress.
* FootPopping: Charlie, kissing his bride at the altar, dressed in a kilt.
* FriendsRentControl: Charlie appears to be a full-time beat poet (and doesn't apparently work very hard at it), and yet can afford a nice apartment in San Francisco. Probably also applies to Harriet and her sister, who have an ENORMOUS loft in the same city.
* GiftedlyBad: Charlie and his poetry.
* GroinAttack: Inverted when Charlie is struck there by a female opponent. He responds in kind and it's shown to have an effect.
* IronicEchoCut: When Rose first meets Charlie, she offers to make him a rather lush and varied breakfast and asks if he wants some. After Charlie agrees, the scene immediately cuts to Rose pouring a bowl of cereal and admitting that she can't make any of what she described.
* LoveMakesYouEvil: The hidden setup as we find out in TheReveal. It is questionable, however, on whether [[spoiler: Rose]], who is the culprit is actually [[LoveMakesYouCrazy insane]] the whole time.
* LuridTalesOfDoom: The entire premise of the film is triggered by a sensational story in the WeeklyWorldNews, which turns out to be true.
* MinorFlawMajorBreakup: This is something of a recurring gag for the main character, and it even foreshadows things that are to come later in the movie.
* MistakenForMurderer: The premise of the film.
* OneDialogueTwoConversations: After overhearing two obituary writers making flippant jokes about recently deceased people who've crossed their desk, Charlie realizes that one of them may be a victim of Mrs. X and tries to find out whether the deceased had a wife. One of the writers thinks that Charlie's rebuking him for his insensitivity. An argument ensues.
-->'''Charlie:''' Did they mention anything about his wife?\\
'''Obituary Writer #1:''' ''[Chastened]'' Alright, okay, look, I know that we're talkin' about real people here, so I'm sorry.\\
'''Charlie:''' No no, I'm serious -- did they mention the wife?\\
'''Obituary Writer #1:''' Look, I'm sorry, you know, I-I-I didn't mean to make a joke about other people's lives.\\
'''Charlie:''' No no, I'm really serious, did they mention the wife? I just want to know about the wife.\\
'''Obituary Writer #1:''' ''[Increasingly agitated]'' You win! You win. I'm a bad person!\\
'''Obituary Writer #2:''' Hey c'mon, take it easy, will ya?\\
'''Obituary Writer #1:''' Well, he's sayin' I'm insensitive! He's sayin' I'm a shit!\\
'''Obituary Writer #2:''' He's not sayin' you're a shit!\\
'''Charlie:''' ''[Trying to get a word in edgewise]'' Did they mention his wife? ''Did they mention his wife?!''\\
'''Obituary Writer #1:''' ''[Losing it completely]'' NO! THEY DIDN'T MENTION THE WIFE! YOU HAPPY?!?! ''[Begins to storm off; everyone's staring at him]'' OH-HO, YES! I'M INSENSITIVE! I'M A BAD PERSON! STOP YOUR JOBS! LOOK AT THE INSENSITIVE MAN! THAT'S WHAT THEY'RE PAYING YOU FOR!
* PrecisionFStrike: When an axe thuds into the dresser right in front of Mike Myers and he shouts "What the Fuck?!"
* UsefulNotes/SanFrancisco: The main setting for the movie (and a lot of it was filmed there as well).
* TalkingInYourSleep: Charlie is awakened by Harriet shouting "RALPH!" in her sleep.
* ViolentGlaswegian: According to Charlie, the Scots have their own form of martial arts called "Fuck-You" which is comprised of "...mostly headbutts, and then kicking the other person when they're on the ground."
* WhatExactlyIsHisJob: Charlie Mackenzie must have a job, right? Some kind of job...other than...occasional poet. Some dialogue early in the film implies that he may own the coffee shop/nightclub/poetry house he hangs out at. (If so, he still seems to be a very hands-off owner.)
* {{Yandere}}: Harriet, who becomes a bit unhinged after winning over Charlie.
** In a subversion, this is because [[spoiler:''all'' of her previous husbands abandoned her and she's developed a complex -- or so she thinks. Turns out Harriet's ''sister'' was an insane {{Yandere}} for ''Harriet''. She murdered Harriet's husbands and faked their deaths to keep Harriet to herself and nearly does the same to Charlie near the end]].
